Re: [ptxdist] How to create multiple packages, which contain same filename ?

["Baeuerle, Florian" <Florian.Baeuerle@allegion.com>]

Hi Andreas,

maybe you can confirm if this assumption is correct:

You are using image packages with your collections to create rootfs images for
your three different variants.

If so, then this probably the root cause:

ptxdist has this "nfsroot" feature. By default, it installs everything into
$build/root. This is a bit problematic when using image packages, because it
will install all your variant packages in parallel. This leads to races where
variant-1 wants to install and chmod a file, but shortly before variant-1's
targetinstall wants to chmod the file, variant-2 replaces it.

Additionally, the content of the nfsroot are not really predictable.

There is currently no option to disable nfsroot (wouldn't be a problem anyway,
because for image packages you can have an nfsroot for each root image you
create). I want to submit a patch (well, at some point...).

If you just need a short workaround, you can place sleeps into your image
packages .targetinstall stages (That's what I do).

variant-1: no sleeping
variant-2: sleep 1
variant-3: sleep 2

It's just an ugly workaround and it can still fail.

Feel free to go ahead and submit a patch, proposal #1 or #2 to fix the issue
probably have chance to get accepted:
